I've included a map below, that I just posted in the weather forum. The Park area is directly behind Xanadu. A number of the roads scoured out in this project actually enter into what is the Park area, but they are barb-wired shut. If the roads in the park are like the roads to Xanadu, a 4WD probably isn't needed, but you would have to have a good, high, rugged jeep or pickup to be sure, not a car. If there are any open roads in. It seems to be more of a forest preserve. There is an entrance to the park from Cabarete. Just past the Tigermart on the right is a sign for the underground Cuavas del Choco or something like that. They give guided tours in several languages, and may give tours into the park as well, I have never checked. I see the tourist trucks up and down El Choco every day. They may enter the park from the El Choco side as well. But they end up usually in Sabaneta at the river.

My apologies if I misinterpreted your intent in deleting your post in the Weather thread. It did not seem to be a serious question at first read.
